11.21 Analog Value Representation for Analog Input Modules in S7 Num-
ber Format
The tables in this section contain the measurement representations for the
individual measurement ranges of the analog input modules. The table values
apply to all modules with the corresponding measurement ranges.
The following tables contain the digitized analog values for the various mea-
surement ranges.
Since the binary representation of the analog values is always the same, the
following tables contain only the measurement ranges against the units.
For the corresponding binary representation of the measured values, see the
tables in Section 11.20.
